high-bypass

high-bypass

An engine with a bypass ratio in the region of 15:1. These engines may be used for reverse thrust. This type of configuration is known as a cold reverse thrust as opposed to a hot reverse thrust, which is provided by hot exhaust gases.

Mitsubishi executives stress that their product is 20 per cent more fuel efficient than other leading single-aisle jets, because it was engineered specifically to work with a Pratt and Whitney high-bypass geared turbofan engine.

The partnership will focus on high-bypass ratio geared turbofan technology and the companies will collaborate on future studies for next generation propulsion systems, including advanced geared engines, open rotor technology and other advanced configurations.

The new high-bypass turbofan engine, incorporating Rolls-Royce's proprietary three-shaft architecture, will have thrust ratings across a range of 74,000 to 92,000 lb and achieve remarkably higher combustion efficiency.
